Vehicle Detector Installation Options
The Smart Touch Controller provides a feature rich interface to four different vehicle detector inputs.
Standard box type 11 pin (24 Volt DC or 24 Volt AC) vehicle detectors may be connected in the
traditional manner, see page 45. Hy-Security also offers a custom mini detector module that plugs
directly into the Smart Touch Control board. Not only is the field installation much faster, but there is also
a large performance benefit. The Hy-Security HY-5A detector is controlled by the Smart Touch
microprocessor to achieve many benefits over common box type detectors*
a. Loop frequency is automatically set and monitored
by the Smart Touch Controller
b. Cross talk between multiple loops is impossible
c. The best operating frequency for each loop is
automatically chosen
d. Smart Touch can report the both loop frequency and
call strength on its LCD display
e. Smart Touch will report loop malfunctions and store
this data in its EEprom memory
f. Most detector or loop faults that could occur are
reported and displayed on the LCD display
There are four vehicle detector inputs available both on the main terminal strip and as direct plug in
modules. The vehicle detector inputs are for the following functions:
1. Free Exit Loop Detector –
“ELD”
2. Outside Obstruction Loop Detector – “OOLD” (this is the outside reversing loop)
3. Inside Obstruction Loop Detector – “IOLD” (this is the inside reversing loop)
4. Shadow Loop Detector – “SLD” (this is for swing gates only)
*A combination of HY-5A detectors and standard box detectors is acceptable
It is not mandatory to use two separate detectors for inner and outer obstruction detection ,
however the benefits of using this additional detector are great. Several new features are possible, such
as 2
nd
vehicle intrusion detection, a loitering alert and selectable non-reversing. Multiple obstruction
detectors may be mandatory because not more than 200 sq-ft of loop area may be connected to any one
detector or the sensitivity becomes inadequate.
